Footwear



FIG. 1 is a perspective view of an article of footwear, showing my new design;

FIG. 2 is a side view thereof.

The broken line showing in the drawing figures is for illustrative purposes only and forms no part of the claimed design.

Any surface of the article of footwear not shown, or any part of any such surface not shown, is not part of the claimed design. 

I claim the ornamental design for an article of footwear, as shown and described.
